Abstract
The presence of gene 16S rRNA and genes encoding toxin A (tcdA), toxin B (tcdB), and binary toxin (cdtA/cdtB) of Clostridium difficile in stool samples from children with (110) and without (150) diarrhea was determined by using a TaqMan system. Fifty-seven (21.9%) out of 260 stool samples harbored the 16S rRNA gene. The genetic profile of tcdA+/tcdB- and cdtA+/cdtB+ was verified in one C. difficile-positive diarrhea sample and of tcdA+/tcdB+ in three C. difficile-positive nondiarrhea samples. The presence of tcdA+/tcdB+ in stools obtained from children without diarrhea, suggests that they were asymptomatic carriers of toxigenic strains.
